At an aquaponics farm in Luxembourg called “Fësch Haff” the effect of the water quality on the growth rate and behaviour of the rainbow trout has been analysed. Three times a week the water quality in the fish tank expressed by temperature, KH (carbonate hardness), pH, ammonium/ammonia, nitrite, nitrate …

In this research there was looked at the connection between the Zeta potential and the pressure sensitivity of a chloroprene dispersion in order to gain insight in dispersion stability. This was done by varying the pH and ionic strength of the chloroprene dispersion. There was also looked at whether …

This paper presents a user-friendly version of Persistent Homology (PH) graph code to model financial market structures and changes. By leveraging Topological Data Analysis (TDA), the code offers an effective approach for analyzing high-dimensional stock data, enabling the identification of persistent …

De EU en Nederland streven naar significante reducties in broeikasgas- en stikstofemissies tegen 2030. De Nederlandse melkveehouderij draagt met respectievelijk 36% en 48% bij aan de broeikasgasuitstoot en de ammoniakemissies van de landbouw. Het aanzuren van mest met zwavelzuur, zoals in Denemarken, …

This paper proposes a novel theory, coined as Topological Tail Dependence Theory, that links the mathematical theory behind Persistent Homology (PH) and the financial stock market theory. This study also proposes a novel algorithm to measure topological stock market changes as well as the incorporation …

Accumulation of non-degradable plastic waste in the environment might be prevented by the use of biodegradable polyhydroxyalkanoate (PHA). In this study, the thermophile Schlegelella thermodepolymerans produced up to 80 wt% PHA based on dry cell mass. The largest PHA granules were found in the cells …

Moneybird beheert meer dan 400 miljoen bestanden in een microservice genaamd Moneybird Storage (MBS). Omdat MBS geen gebruik maakt van frameworks maar door Moneybird is ontwikkeld voor de eigen use case, valt de gehele onderhoudslast op het development team. Het Rails framework waarop de meeste code …

Sodium-glucose co-transporter 2 (SGLT2) inhibitors, including canagliflozin, reduce the risk of cardiovascular and kidney outcomes in patients with and without type 2 diabetes, albeit with a large interindividual variation. The underlying mechanisms for this variation in response might be attributed …

Standard SARS-CoV-2 testing protocols using nasopharyngeal/throat (NP/T) swabs are invasive and require trained medical staff for reliable sampling. In addition, it has been shown that PCR is more sensitive as compared to antigen-based tests. Here we describe the analytical and clinical evaluation of …

Rhodomonas salina is a microalgal species, belonging to the cryptophytes, and is widely used as aquaculture feed because of its high nutritional profile and phycoerythrin content. This study investigated the effect of pH on the growth, biochemical composition, and taste of R. salina when cultivated on …
